Title: Reference position setting method for throttle valve opening detector
Inventor: ONO NOBUYUKI
IPC: F02D45/00
Filed: 1990-03-28
Abstract: PURPOSE:To reliably set a reference position on a basis of which a valve opening is detected by energizing a current of a given value, at which a throttle valve is rotated and displaced to a fully closed position, to a motor for a given time, and resetting a counter after a lapse of the given time. CONSTITUTION:When an ignition switch is brought into an ON-position, energization of a DC motor 16 with a current having a given value at which a throttle valve 12 is rotated toward a fully closed position is started. Energization is effected during a given time in which the current is clocked by means of a timer 18, i.e., during a time in which a reference position set completion signal is outputted from the timer 18. Thus, the throttle valve 12 is locked to a stopper 13 and positioned in a fully closed position. Thereafter, upon a lapse of a given time, a counter 15 is reset by means of a reset signal outputted from the timer 18. A controller 17 energizes a DC motor 16 by means of an output signal from a car speed control device, and the throttle valve 12 is driven with the aid of the DC motor 16.

Title: Diaphragm
Inventor: UENO TAKAFUMI
IPC: H04R7/02
Filed: 1978-06-30
Abstract: PURPOSE:To secure a low distortion in a wide band by giving the light weight and a high rigidity to the diaphragm by loading the micro hollow ball substances into the basic material. CONSTITUTION:The diaphragm is composed by loading micro hollow ball substances 12 such as the silica balloon featuring the hollow inside and the outer part covered with the outer shell plus a high intensity into basic material 11 such as the thermosetting epoxy resin or the like. The specific gravity of substance 12 is extremely small (0.05-0.5), and accordingly the thickness of material 11 becomes 1.8 times as large as the basic material only after loading of the ball substance and under a fixed overall weight under the conditions of, for example, 1.0 specific gravity of material 11, 0.1 specific gravity of substance 12 and 50% volume ratio of the loading quantity of substance 12 respectively. Flexural rigidity Y features as Y=E.t<3>/12, where Young's modulus is E and thickness is t each, which means about 1.8<3> (5.8-fold) compared with the flexural rigidity of material 11 only. As a result, a diaphragm featuring a low distortion in a wide band can be obtained with the light weight and an extremely high flexural rigidity.
